Fig. 7 is a horizontal section taken on the line 'I-1 of Fig. 5 asindicated by the arrows; and

Fig. 8 is a vertical section taken on the line il-G of Fig. 5 asindicated by the arrows.

Referring rst to the embodiment of the invention shown in .Figures 1, 2,3, and 4, there is provided, a container il, having a reduced mouth atits upper end provided with external screw threads 9a and an inturnedange 9b at its top. There is also provided a cap Ill, having a circularskirt portion Illa, provided with internal screw threads for releasablyengaging the external screw threads 9a at the mouth of the container s.The cap I0 has a lateral projecting portion Illb of fiat construction,the sides of which taper toward the end of the projecting portion as'best shown in Fig. 2. It should also be noted that the edges Illc, ofthe cap I0 above the skirt lila project outwardly beyond the skirt for apurpose presently to appear. The cap Il] also has an upwardly extendingportion Illd, provided with external screw threads at its outer end,whereby a spout II may be attached to the upwardly eX- tending portionIlld, as by a suitable fitting, t2. In the form shown, the upwardlyextending portion IIld is tilted at an acute angle relative to the bodyportion of the cap I0, but it will be understood that the portion Id maybe extended at any angle from the body portion of the cap so that avertically extended spout, for example as shown in Fig. 5, may beapplied thereto, or a spout 2 Claims. (Cl. 222-385) l disposed at anyangle fill* may be applied thereto. A passage is formed'through the bodyof the cap Ill and through the upwardly extending portion IUd, wherebycommunication is afforded through z the cap with the spout I I.

A conduit I3 is"A screw ythreaded into the lower part of the cap, thepassage through the body ci" the cap being enlarged and tapped toreceive the upper end of the conduit I3. This conduit I3 is preferablyprovided with a double bend as shown in Fig. 1, and runs down toa pointnear the bottom of the container 9, somewhat forwardly of the verticallongitudinal center line of the container.

The conduit I3 supports a pump structure within the lower part of. thecontainer Sl. This structure includes a pump body It, forming a pumpcylinder I4a within which a pump plunger I5 works. An inlet I4b into thelower end of the cylinder Mais provided and this inlet is controlled bya ball valve I6, spring pressed into engagement with its seat by aspring I 1 reacting between the ball I6 and the lower end of the pumpplunger I5. The pump body I4 vis also provided with a lateral outlet I4cat the lower end of the pump cylinder I 4a, and this outlet iscontrolled by a ball valve I8, disposed within a horizontal bore idd inthe pump body and pressed into engagement with its seat by a spring I9,reacting between the ball valve I8 and a screw 2l] closing the end ofthe bore I4d. The lower end` of the conduit I3 screws into a lateralextension of valve body Hl above the bore Idd and vthis lextension isprovided with a vertical bore I 4e whichaiords vcommunication lbetweenthe bore Ifd andthe conduit I3.

The conduit I3 is provided with a cross bore slightly above the level ofthe pump cylinder lila, and fitting within this cross bore is a smalltube 2 I, which is sealed at its ends to the sides of the conduit I3 sothat oil or other fluid within the container 9 cannot seep into theconduit i3 through thebore within which the tube 2| is located.V A pivotpin 22 fits through the small tube 2I and acts as agpivot for a doublearm lever i 23. lConnected at one end, by a pivot 24 to the double armlever 23 Vis a short pitman 25, having a ball at its lower end fittingwithin e. ball socket I5crl at the upper end ofthe plunger l5. Thus, thelower end of the pitman 25 is capable of universal movement relative tothe plunger i5.

Connected by anotherpivot 25 to the opposite end of the double armlever` 23 isa rod 21, which projects upwardly through a small openingite in the cap I0 and this rod is provided with an enlarged head atitsvupper end. A wiper gasket 28 surrounds the rod 21 immediately below theopening Ille and this gasket tends to wipe the upper portion of the rodclear of oil as the rod is raised. A coil spring 29 ts around the rod 27and reacts between the gasket 28 and the pivot pin 26. In the form ofthe device as shown, the three pivot pins 22, 24, and 26 are shown asbeing cotter keys but any type of pivot could be substituted therefor.

The cap Ill'carries agasket 'which normally rests onfthe flange 9b ofthecontainer '9 so-that the cap will form a tight seal with the mouth ofthe container.

Overlying the major portion of the cap and the extension |b thereof is asheet 3|, this sheet being apertured to receive the upwardly extendingportion |0d of the cap and .the edges of the sheet being crimpeddownwardly and portions thereof inwardly to embrace the extended rimlilc of the cap and the extension Ib thereof. The edges lof thesheet l0.are lbent inwardly-on themselves, outwardly strom :the extension 0b 4toform a handle 31a, ithis .handle outwardly :from the extension |0bbeing. .first idownturned and then reversely curved as shown in Fig. 1.The metal of the sheet3|.:iscutltorform Aa .tab 3|b and this tab islswung Aupwardly `and a-:channel shaped slot 3| c is formed.thereimwhereby the tab will form a fulcrum .ffor .-a-channel -shapedtrigger lever 32. .This .trigger lever is :formed with a reversecurve-:fas ybest .seen in Fig. l. The iianges at the .sides of thelever-.are ireduced in width slightly at the flower eend fof `the lever.At this point the lever is provided with a Vslot 32a which receives thevupper part-"of the rodv `21 below the enlargedhead thereof. Theupperpart of the trigger lever y32 A`is Asilattened fand ,rounded so asto form a convenient thumb vcontacting portion when .theywholefoilccanis-supported yfrom the handle -3|a by-.one hand @of ftheoperator.

When the oil-Canis .so heldvfandsthe upper part of the trigger lever 32is depressed -by the -thumb of the operator, the triggerfllever 432-will .'have a sliding action relative to lthe tab 3|b. as the rod 2l israised .by Athe .normally lower .portion of the lever. Of (course, asthezrod 21 ris raised against the ltension ofthe spring `29, the lever 23will be swung .so .as to `depress the pitman 25, thereby depressingthepump plunger |15 and ejecting oil cont-ained inthe ,pump :cylinder|4ll through the `outlet rHc, :into the bore Md and bore 4e, causing the-oi1 -tovbe .forced upwardly through the conduit i3, rpassage through.the 'cap i6 and spout .As-thevtrig'gerlever 32 `is-released by the.thumb .of .the -nperator 1the Y spring 29 will return the parts `to the.position shown in Fig. 1, thereby .causingthe ;plunger |.5 A.to moveupwardly, closing Athe .valve 5|8 land `opening the valve |6 `and.sucking a .fresh supply of oil into the pump .cylinder lla.

The ball and .socket joint connecting the pitman 25 with the pumpplunger|5 4allows -for proper movementof the -partswithout a .loose connectionand the use of `the .small tube-2| mounted in .the conduit .I3 .permitsthe lever 23 to be readily supportedfromthe conduit .i3 without seepageof oilinto the-conduit .|l3.

In practice '.thefcap `AIll .will :be .die-cast in one piece andthepartsare thus very easilyassembled with a minimum of-labor.

Referring now to .'Fig'uresv, 6, .7 ,and l8 of -the drawings anotherembodiment of "the invention is shown which .includes-.many ofthefeaturesof the device illustrated in`Eigures` 1 .to 4. .In'the deviceshown in Figures 5 'to 8,1 :a lcontainer 33 is provided, having a mouthwith external screw threads to which there is threadedly secured a cap34, there being a gasket 35 interposed between the top of the container33 and the cap. Fitting loosely through a central aperture in the cap 34is a fitting 36, having a shoulder of polygonal shape to receive awrench above the cap and below this shoulder the tting 36 is reduced andscrew threaded to pass through the aperture in the cap and Ato receivebelow the same a gasket 3'! and nut 38. The portion of the fitting 36below the shoulder is cut away and 'flattened at its sides to correspondto the shape of the aperture through the cap 34, whereby parts attachedto the tting 36 may be properly aligned relative to the spout which willbe later described. Above its shoulder the tting 36 is provided withexterior screw threads to receive another `iitting 39 securing a spout49 in position on the tting 36. Of course, the tting 36 is provided witha :passage therethrough communicatlng with the spout 40. The -passage inthe lower part of the tting 36 isenlarged and tapped to receive thescrew threaded upper end ol a conduit 4|, which projects down into thecontainer 33 and carries at its lower end apump structure. The said pumpstructure includes a pump body 42 forming a pump cylinder v42a withinwhich works a pump plunger 43. An inlet 12b is provided in the lowerpart of the pump cylinder 42a and this Iinlet is -controlled by a ballvalve 44, pressed into vposition by a coil spring 45 reactingbetween'the ball 44 and the pump plunger 43. As in the case-of the pumpstructure previously described, theretis an `outlet 42o formed in thelower part of the pumpcylinder 42a and this outlet is controlled by aball valve 46 disposed within ya horizontal bore 42d in the body 42,`the ball 46 being normally held into engagement vwith its seat by acoil `spring 4l, reacting between the ball -46 and a screw 48 whichcloses the bore 42d. The bore 42dcom municates with a vertical bore 42ein the pump body 42 and the lower end of the conduit 4| is screwed intoa portion-of the body 42 immediately above the bore 42e, so thatcommunication may be aiorded through the bore v42e with the lower end ofthe conduit 4|.

The body 42 is slotted at -4'21 near its upper ,end to 4receive atwo-part lever 49 pivoted in apair of projecting ears '42g formed onthevalve body 42 at the two sides of the-slot 42f. The `lever 49 has atone end, the upper end of a pitman 50, pivoted thereto, the lower end-ofthis pitman being ball shaped to fit -within a .socket at the upper endof the plunger 43. A rod 5| is pivoted to the other end of the lever 49and this rod projects upwardly through a wiping gasket 52 and through anaperture in the cap 34 .and is provided at its upper end with'anenlargedhead. Avcoil spring 53 surrounds lthe rod 5| and reacts between thegasket 52 vand the pivot connecting the lower end of the rod to thelever-49.

Spot welded or otherwise secured -to the top of the cap -34 is a handlemember'54 and the inner end of this handle member is notched to -embracethe cap 34 at two sides of the tting 36. A tab 54a is bent upwardly fromthe notched portion and this tab is provided with a `channel shaped slottherein, -receiving trigger lever 55 of -similar construction to triggerlever-3f2 previously described. The lower 'end'of the trigger lever 55is apertured to receive the lupper part-of the rod 5| below the enlargedhead thereof. The handle member l54 is curved as Ishown in Fig. '5, soas to form a proper support for the hand of the operator withoutpermanent engagement with the side of the container 33.

The operation of the device shown in Figs. to 8 will be readilyunderstood. The construction of the cap 34 and fitting 36 together withassociated parts is such that the cap 34 may be merely a stamping andthe parts can be assembled readily without soldering or weldingoperations.

While the devices of the invention are intended primarily for use ashand oilers, it will of course be understood that the structuresemployed may be used in dispensing any kind of iiuid, such as water,cream and all kinds of lubricants.

It will be seen that highly ecient hand oiler structures have beenprovided. It will of course be understood that various changes may bemade in the form, details, arrangement, and proportions of the Variousparte without departing from the scope of the present invention which,generally stated, consists in the matter shown and described, and setforth in the appended claims.
